The preferred brand is Fujitsu Lithium 6 volt, type CRP2. In use this battery has proven to have a greater capacity than other brands, giving proper solenoid operation within the voltage warnings provided by the electronics and for longer life.
Medium - 11.4kg (5.7 litres per counterlung)Large & XL - 14 litres (7 litres per counterlung)
Two 2-litre steel cylinders, one oxygen, one diluent (M25 x 2 cylinder thread, 3/4" NPSM - USA)
40m - max. Depth with air diluent.100m - max. Depth at which all rebreather parameters are proven: CO2 endurance, O2 control and work of breathing.100m - the limit of the CE approval.110m - max. Depth at which the work of breathing has been tested using Trimix diluent.
150m - max. Depth at which the work of breathing has been tested with an Heliox diluent.
160m - Depth at which all components are pressure tested during type approval (not during production).
WARNING! Diving deeper than 100m carries the following additional risks.
Deeper than 100m: CO2 endurance unknown.Deeper than 100m: Onboard decompression invalid.
Deeper than 110m: Work of breathing with a Trimix diluent unknown.
Deeper than 130m: Depth gauge inaccurate.
Deeper than 150m: Work of breathing with an Heliox diluent unknown.
Deeper than 160m: Structural integrity of components unknown - the air cavity within the buzzer will implode eventually, and other components may fail.
Two oxygen pressure setpoints, switchable from low to high and high to low as often as required, both underwater and on the surface.

The rebreather operating temperature range is determined at the cold end by the CO2 duration trials, which are done at 4°C(±1). Below this temperature the duration of the CO2 absorbent has not been empirically determined. If stored below 0°C the CO2 absorbent and electronics will
need gentle pre-heating prior to use by placing in a warmer room or by
submersing the assembled rebreather with mouthpiece closed (loop sealed) until the temperature of the equipment matches the ambient temperature. Below 0°C the liquid crystal display in the handset freezes to a solid black and is unusable. Water is an essential part of the CO2 absorption reactions (approx. 17% of Sofnolime is water), below freezing point the first reaction where CO2 and water react to form Carbonic acid cannot take place. If a pre-breathing method of warming the Sofnolime is used, this must be done on land under supervision.
When stored in accordance with BS3574 the shelf life is 7 years. (derived from the hoses and seals)

DEPRESSION AND ANXIETY 14:149–152 (2001) EMETOPHOBIA: PRELIMINARY RESULTS OF AN INTERNET SURVEY Joshua D. Lipsitz, Ph.D.,1,2* Abby J. Fyer, M.D.,1,2 Anthea Paterniti, B.A.,1 and Donald F. Klein, M.D.1,2 Through electronic mail, we surveyed members of an internet support group for emetophobia (fear of vomiting). Respondents were 50 women and 6 men with a mean age of 31 years. Results
